14.3.3
The POR LVcore and POR LVmem reset sources are merged to provide a single reset
source, POR LV, to the Reset Generation module, since the detection of either event needs
to reset the same system modules.
NRST pin
A single active low pin, NRST, is provided to reset the system. This pin has a Schmitt
triggered input.
To afford good noise immunity and resistance to switch bounce, the pin is filtered with the
Reset Filter module and generates the reset source RSTB to the Reset Generation module.
Table 139. Reset filter specification for RSTB
Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, LU) using specific measurement methods, the device is
stressed in order to determine its performance in terms of electrical sensitivity.
Electrostatic discharge (ESD)
Electrostatic discharges (a positive then a negative pulse separated by 1 second) are
applied to the pins of each sample according to each pin combination. The sample size
depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test
conforms to the JESD22-A114/C101 standard.
Table 140. ESD absolute maximum ratings
1. Based on characterization results, not tested in production.
2. Value valid for all devices and all pins except for the RF pins of the STM32W108CC and STM32W108CZ
3. Value valid only for STM32W108CC and STM32W108CZ devices.
